Hi,
I'm using Nginx 1.8 and trying to add a sub_filter but It fails to work (I don't see the substitution happenning).


location ~* \.(appcache|manifest)$ {
expires -1;
rewrite ^(/v[0-9]+/.*)$ /app_ver$1 break;
rewrite ^(?!/v[0-9]+/)(.*)$ /app$1 break;
proxy_set_header Accept-Encoding "";
sub_filter 'CACHE' 'CACHE22';
sub_filter_once on;
proxy_pass http://static.dev.capriza.com.s3.amazonaws.com:80 ;
}


You can see below that the sub_module is there:

root#2>&1 nginx -V | tr -- - '\n' | grep _module
http_ssl_module
http_realip_module
http_addition_module
http_sub_module
http_dav_module
http_flv_module
http_mp4_module
http_gunzip_module
http_gzip_static_module
http_random_index_module
http_secure_link_module
http_stub_status_module
http_auth_request_module
mail_ssl_module
http_spdy_module

Any idea what may be wrong here?

Tx,
Yuval
